Hi Leeboy
Music Store has recently appointed an official Wersi Service Partner in the US http://www.wersi.net/service.html (As I have posted previously) scroll down the list.

The prices quoted for the Wing, are significantly cheaper than most of the other TOTL Arrangers out there, (It’s even cheaper than a PA2x) so may not be out of reach like you think. (Just don’t expect any entry level or Mid-Range priced instruments)

MusiKMesse 6th – 9th April should give you an idea of where it’s going, and you will also be able to compare it to the New PA3x which should have the Official Release OS installed by then. (Don’t forget to also compare it to the more expensive but really cracking T4 and the Audio Style Based Audya)
